Description

Technical Field

[0001] This invention relates to the field of nondestructive testing technology, and more specifically, to an automatic imaging testing device and method for clutch-type disk ultrasonic phased array. Background Technology

[0002] Disk components are among the most critical parts in aero engines. Some newer engines employ welded integral bladed disk structures, connecting the blades and disk core using diffusion welding or linear friction welding techniques. The quality of the weld directly impacts flight safety. To control weld quality, highly sensitive ultrasonic testing of the weld area is necessary.

[0003] Due to obstruction from structures such as blades, ultrasonic waves cannot be incident from the circumferential direction. It is necessary to incident from the end face of the disk, employing single-probe pulse reflection technology or dual-probe one-transmitter-one-receiver technology for ultrasonic testing. However, most conventional ultrasonic testing equipment for disks uses a horizontal structure, which cannot meet the requirements of dual-probe testing. Furthermore, to meet coverage requirements during testing, the dynamic deflection and focusing functions of an ultrasonic phased array are required, which is also lacking in conventional ultrasonic testing equipment for disks. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the present invention aims to provide an automatic imaging detection device and method for clutch-type disk ultrasonic phased array. On the one hand, it is convenient to load and unload the disk and probe under test without damaging the structure of the disk under test. On the other hand, it fully considers the characteristics of ultrasonic phased array detection technology and is suitable for two working modes: single probe pulse reflection detection and dual probe one-to-one transmission and one-to-reception detection, thus meeting the high-sensitivity ultrasonic detection requirements of welded integral bladed disk weld seam area.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0034] 3. Beneficial effects

[0035] Compared with the prior art, the advantages of this invention are:
